Science Rock! is the fourth category of Schoolhouse Rock, that goes over different types of science.

Sometime after its initial airing, The Greatest Show on Earth, also known as The Weather Show, was pulled from broadcast rotation because the Ringling Bros. & Barnum & Bailey Circus objected to its use of their trademark slogan (which was in the questioned title) & filed a lawsuit against the network for copyright infringement. As a result, the 1995 VHS of the program (& subsequent VHS reissues) deleted the song. However, it was included in the 1987 Schoolhouse Rock VHS release, & in 2002 it was included on the bonus disk of the 30th Anniversary DVD.
